The first big catch and more biscuits

Two very successful days for the arctic brent research team as we have caught on both days on land, water and air. The geese can run but they cannot hide, or fly away.

The first catch was done at a nearby Great South Lake and involved setting our net on land at the far shore and driving the geese by paddling two zodiacs towards them. There were only 3 geese on the lake, but it was a nice day for boating. Alan and Kerry set the net with two long wings and a central holding pen with a door. Tom and I were in one boat with Graham and Chantelle in the other. Chantelle is the best and most experienced at using these boats so she gave us some pithy advice on rowing before promptly falling in the water as the boats were launched. Graham and Chantelle rowed a wider arc down the lake than us were the water was still. In contrast, Tom and I tried to hug the ice upon the lake on our route and battled bravely against strong currents and icebergs. We successfully drove 2 birds into the net between the combined boat and land teams. The third goose flew away, which hardly seems fair. As we pulled the boats from the lake Chantelle fell in the muddy shore, but she is the most experienced boater amongst us so we were not worried. One bird was already ringed JLLY and presumably the other birds was its partner,. All that was left afterwards was a reasonable walk home.

Catching 2 birds is great but today we went 'nuclear' and brought the chopper in. Alan, Kerry, Tom and I got the helicopter in the morning and went  scouting for geese and catch sites. Chantelle and Graham were to be flown in after we had caught to help measuring the birds. Initially it looked bad as all the places we had seen geese were deserted. However, we eventually saw a large flock of adults that would be a good target. The net was set quickly and then we lay down 2 people at the end of either wing of the net. In the meantime our pilot John Innes drove the flock from further along the coast to our net. The geese approached quickly but were reluctant to enter the net to the point that some brave geese stopped and sat down just metres from the helicopter. The four of us sprang into action to encircle the geese while the rotor blades thundered overhead and grit from the  the downdraft lashed our handsome faces. I am sure to bystanders it looked really cool, or would have if there had been any. In total , we got 73 with 4 escapees. Credit to John who did most of the work. Catching was quick but processing the birds took longer, but John helped and seemed to enjoy his role of passing geese to folk. Some birds already had rings but most were birds we had already caught this trip, so the geese may be forming larger flocks . Some females may have been failed breeders as well judging by their plumage. So, a great day with some stupendously brave little geese.

Back at camp we opened some new Maxi Fruit biscuits. They are soft oatmeal with a jam filling and are bordering  on cake territory. They fall just short of the maple creams in our biscuit pantheon, but still a nice treat after our success. Of course, once we return to Resolute the biscuits will be off the chart.

Long walks and goose families

Over the past few days we've initiated the new guys in camp with a series of brutal marches in order to find moulting flocks of geese and geese families. On the plus side we have seen  a lot of the major bird species and, judging by people's reactions, Sabine's gull and snowy owl were the highlights. On one walk we were also followed for several km by a musk ox who occasionally blocked our way, but who was sent running by loud noises.

Ultimately, we found several groups of moulting birds and  a few families. In particular, we discovered a group of 3 families with 5,4 and 4 goslings respectively. In one family the goslings were noticeably larger and therefore older than the others.

The next day Kerry and I (and note I say I rather than myself now - thanks to those who criticized and corrected me before) walked back to where the families were to attempt some behavioural observations. We had to watch from a km away as they were easily spooked. Also, the family sizes now were all 4 so one gosling is gone  already.. The group is pretty chaotic as the goslings charge around and often congregate in a large group leading to aggression between adult pairs. Watching the adults it appears the female spends more time feeding than the male. However, other variables may be important. For example, after being frightened by a snowy owl feeding rates dropped and birds were more watchful. Feeding rates were also observed to increase when birds fed in lush pond-side vegetation. Adults also spent some time preening. The goslings were either grazing or running around the whole time. All fairly anecdotal but lovely stuff.


We have the helicopter booked for most of the 26th July and the team are planning some big catches. Updates on that very soon. BTW I think it is Barb that has been giving Ian a hard time about his grammar...

Back in Eureka (albeit very briefly)

We are currently back at the Eureka weather haven resting after our two weeks on the Schei. Funnily enough the haven now feels more luxurious than it did previously. I am particularly overjoyed to return to my greenhouse room, which is always warmer than everyone else's. The folks down at the weather station were kind enough to offer us a free shower and laundry, So we are clean and well-rested. There has also been a change over of field workers. Freydis and Sean have returned home after some great work, including two textbook goose catches and a mysterious event I am calling the 18 goose enigma. In their stead Alan, Graham and Kerry have arrived for the third section of the field season. Here is a photo of all of us together with one of our helicopter pilots Stig. The next phase of work will involve camping back out on the Schei, but will end with us staying in Resolute where you can get pancakes for breakfast - a thought we often find cheering.

Hatching, broken quads and mosquitoes

A fun-filled few days encompassing the full spectrum of human emotion. From the highs of catching geese throught the lows of broken quad bikes to warm still days and plagues of mosquitoes. A couple if days ago we had a break from routine in the Schei Camp as we had a helicopter flight to check the status of the nests we found and retrieve the temperature loggers we placed in each nest. On the flight to distant Axel F we also saw a wolf and an arctic fox. All in all most of our 24 nests appear to gave been successful with 4 falling victim to predation. Gulls may be the most likely cause as we found eggs with holes punched through them at the nest.
On True Brant island we saw nest where the female was still sitting but with one gosling scrabbling and squeaking in the nest trying to get under her wing. We also saw several families walking their goslings from the island out on the sea ice. While on Gerry Murphy Island the abominable yellow sludge has mellowed into spongy sand. Here too we saw a female on the nest with her chicks. So hatching success has been pretty high, although Tom noted on the flight up to the breeding islands that there were very few family groups (but lots of non-breeder moulting flocks).

Yesterday we attempted our second catch at the awkwardly named 13 goose pond complex. We were aiming for all 13 geese. Catching involved herding them from one small pond across a bit of land into a smaller pond and then into the net. It soon became obvious that we would have to get wet to get them off the first pond as they were happy to circle in in the middle of it. In the end, Sean (our hero) swam at the geese while everyone else waded in and we forced the birds into the smaller pond where it was simple to close the trap. On land the geese are quick despite their comical gait. We caught all 13 including yet another retrap!! FU White White (phnar phnar) was originally ringed at Strangford.

Alas, our beloved red quad broke down at the catch site and even duct tape could not revive it. Consequently, we had to lug everything back 10 km to camp. It was good exercise in a way and never far from being fun. Kerry, Alyn and Graham are all due to arrive in Ottawa late tomorrow and fly on to Resolute on Friday. The airstrip there has been fogbound for the last three days, so fingers crossed they get in.

The first goslings and a Cadburys pair are retrapped!!

Sometimes when conducting fieldwork a lot can happen in a short space of time. Yesterday, myself, Chantelle and Freydis went in a trek across the peninsula to an inlet we thought looked interesting on the map. After a long walk on which we saw nothing of note except musk ox and grey plover we reached the inlet and we're ready to turn back disappointed. But then across the inlet we saw a pair with 3 goslings. Upon seeing us the adults began honking and led to the chicks into the water and then onto the sea ice. The goslings are small, grey and cute and we roughly estimate they are 3-5 days old.

Today , we attempt to capture 7 geese that we keep seeing on a small lake nearby. 5 of these birds we are sure are moulting and flightless, but the other 2 arrived later so possibly can fly. The lake is small and roughly circular with thin sea ice in the centre restricting the birds to a narrow channel between the shore and the ice. The plan is a pincer movement.with Chantelle driving the geese using a Zodiac boat from the top of the lake down towards our net in the bottom left on the shore. Myself and Tom were hiding on the shore but when the geese pass by we appear and help drive to the net on the corner. Freydis is in another boat acting as a backstop to prevent geese from swimming past the net.
Sean walks out to close the gap between himself and Freydis and we advance closing the trap and drive the geese onto to the shore into the net. At the last minute 2 geese remember they can fly and escape easily but the other 5 are caught. 2 birds caught have rings already (BTRR and ZPWB) and are a pair. They were previously caught at the Cadburys pitch and putt in North Dublin back in February. The whole process was very quick; credit to Sean for the master plan.

Afterwards we celebrate by opening our special maple biscuits. They are like custard creams but maple-shaped and filled with a maple-infused custard cream. They are by far our finest biscuit.


PS from Stu... the maple custard creams are not that great......

Schei Camp Established

Our new camp is now successfully up and running on the Schei peninsula (coordinates: N 80 07.699' W 88 10.914'). The camp comprises one mess tent and 5 personal tents. The personal tents are quite spacious and comfortable considering we are sleeping an inch from Arctic tundra on the fringes of civilization. Around the camp we have a tripwire bear fence that Tom has inadvertently tested on a quest for water. 

Near camp we found some small lakes where we saw goose droppings and footprints suggesting geese eat here. The lakes are fringed with a small green plant that looks similar to the salt marsh plants the geese eat in Ireland. There are also some areas of bog that really stand out as they are shockingly green. However, the essence of the Schei is the combination of musk ox skeletons and wolf prints that litter the ground.

Today we inflated one of our zodiac boats and myself and Tom tested it on a nearby lake. Unfortunately, one of the rollocks was broken making rowing difficult, which may have made us look less competent rowers than we truly are. In the end we adopted an Indian- canoe rowing style that kind of worked until the wind was against us. We rowed frantically against the wind but moved very little and eventually gave up in disgust and went back to shore. Nevertheless, a valuable lesson in the importance of well maintained. 


PS from Stu

I am pretty sure the green plant Ian mentions is the same as Alyn Walsh and I found in 2007 an it looks like some sort of Puccinellia species...

Also I have added some google earth maps to show where everything is:

New nest found!!!

Now that Stu has departed from Eureka it's time to give the blog some more variety with a series of special guest authors. Freydis and Sean have joined our happy team and have been busy getting familiar with the place and the local wildlife. The rest of  us have got a bit blasé about musk ox, how did it ever come it that?

Yesterday in a visit to the weather station we are astounded by news that someone (Nicholas Handspiker) has found a nest nearby. Nicholas even provided photographic evidence to satisfy the cynical. Although he's unsure of the exact location he points out the probable area. After 2 unsuccessful transects - on of which we force Nicholas to help with - we find the female on the nest. The female remains close as we measure the eggs (see pic) an even returns to sitting immediately as we return the last egg. Two of the eggs are cracked and flaking and you can hear the chicks pipping clearly. So, one extra nest and within 1.3 km of our weather haven (n=24). We celebrate by eating toast for lunch. Tomorrow our camp departs for the Schei peninsula.
